After cleaning burner assembly and the lower casting
of grill, reinstall burner to lower casting.
In many areas, spiders or small insects have been
found to create "flashback" problems. The spiders
spin webs and/or insects build nests in the grill's
venturi tube(s). The web and/or nests can lead to gas
flow obstruction, which can damage your grill as it
results in a "flashback" (a fire in the venturi tube(s).
The grill may still light, but the obstruction does not
allow full gas flow to the burner. Therefore, some gas
will back up and escape at the venturi air shutter. This
will ignite, causing flashback, which could also
damage your grill (see Fig. 20 a, b).
TURN YOUR GAS SUPPLY (LP OR NAT)
ON AND TEST ALL FITTINGS FOR LEAKS.
BEFORE ATTEMPTING TO LIGHT GRILL,
BE CERTAIN BOTH VALVES ARE IN THE OFF
POSITION. TURN GAS SUPPLY ON (leaving both
control knobs in the "OFF" position). CHECK ALL
CONNECTIONS WITH A SOLUTION OF 50% LIQUID
SOAP, 50% WATER. SOLUTION CAN BE
SPRAYED ON WITH A SPRAY BOTTLE OR
PAINTED ON ALL CONNECTIONS WITH A BRUSH.
IF BUBBLES APPEAR, TURN OFF GAS, TIGHTEN
FITTINGS AND TRY AGAIN. BE SURE ORIFICES
ARE ENGAGED INTO THE BURNER VENTURIS.

3. The exterior of your grill has been powder coated
and baked with a special high temperature powder
process that seals the paint to the grill housing. The
grill will retain its appearance with a little care.
Occasional white oxidation may be washed off with a
mild soap and warm water. Once oxidation is
removed, turn your grill burners to low heat, close lid
and allow to heat up for FIVE MINUTES. After grill
housing is WARM apply a small amount of vegetable
oil or PGS Stainless Steel Cleaner with a clean lint
free cloth and apply evenly to grill housing. This
method will keep your grill looking new for many years.

Your PGS grill has fine mesh brass screening placed
around the burner venturis to minimize this problem.
Please DO NOT damage or remove these screens
when you clean your burners.
We also recommend keeping your grill covered at
all times, when not in use.
If you live in an area where spiders are plentiful, you
should make it a point to clean the venturis often. You
may want to spray around the bottom of your base with
an insect repellent on a regular basis. You may also
put MOTHBALLS in the bottom of your base.
PLEASE BE CERTAIN TO KEEP THEM AWAY
FROM ANIMALS AND CHILDREN.
For stubborn cases, high temperature touch up paint
can make an old grill appear new. Allow 24 hours for
paint to dry before using grill.
4. If your pedestal is black galvanized steel you can
protect this with a car finish protectant. If you have a
stainless support use a good grade of stainless
cleaner such as our PGS "SSC" (Stainless Steel
Cleaner).

5. To maintain cooking grids, we recommend
brushing with a grill cleaning brass brush after grill has
completely cooled. A light vegetable oil on grids just
before cooking will prevent food from sticking to the
surface. NEVER PLACE COOKING GRIDS IN A
SELF-CLEANING OVEN. If grids are very dirty, you
may want to see your PGS Dealer for a commercial
quality grid cleaner. Be sure to oil before using.
